PSP has always had email access in the form of its browser, though you would only be able to use it while connected to a wireless network. As for the keyboard, there isn't any official one as far as I know, but there have been third party ones which attach in a similar fashion as the one on the PFP. They never really caught on for whatever reason.

The PFP...a natural amongst its own kind.
The PSP....a real portable game console.
That all depends on what you ask of me thinking of what to get.
I still think the PSP is pretty awesome!
It is part of my goal to get one badly...and needly.
I wouldnt know what to do with it when I get it though.
I wonder if you can IM through it too.

I think the creator was a BIG gamer.
For the role-playing girl games that come out in Japan(only).
I am glad that the creator, along with others, made this anime happen!
Thank you also, to Crunchy Roll for bringing it here for us!

make it a small handheld pc meant for gaming, you know like if i wanted to play WoW or Guild wars 2 or be able to pop in normal psp games, or google something and have be able to have online chat groups

As far as I know the PFP is a fictional system. I have handled several Japanese PSP 3000 and PSPgo systems and I can tell you that there is no slide-out keyboard on either. Also, the PFP, according to the manga, connects to the internet and email through the Japanese version of 3G (cell service) which is another feature that the PSP does not have.

However, the upcoming NGP "Next Generation Portable" seams to support most of the features of the PFP in TWGOK. The front touch screen will support an onscreen keyboard and the system will feature both wi-fi and 3G connectivity. Perhaps Sony took a few pointers from the manga? lol

yeah, the pfp is fictional, in japan, they thend to avoid user right trouble, in many manga who have a lot of reference (hayate and gintama) they either censoring some kanji when dealling with other compagny reference, or do some minor change like bwuentendo eeowii.

I dont remember if they show it yet in the anime so i mark the next line a spoiler. If my memory really failled me, pm me so i can remove the alert.

Spoiler Alert! Click to show or hide

the only thing the pfp do more than the npg is having a virtual helm extention
